Looks up a protocol entry based on protocol's number.


#include <prnetdb.h>

PRStatus PR_GetProtoByNumber(
  PRInt32 protocolnumber, 
  char* buffer, 
  PRInt32 bufsize, 
  PRProtoEnt* result);


The function has the following parameters:

The number assigned to the protocol.
A pointer to a scratch buffer for the runtime to return result. This buffer is allocated by the caller.
Number of bytes in the buffer parameter. The buffer must be at least PR_NETDB_BUF_SIZE bytes.
On input, a pointer to a PRNetAddr structure. On output, this structure is filled in by the runtime if the function returns PR_SUCCESS.


The function returns one of the following values:

  • If successful, PR_SUCCESS.
  • If unsuccessful, PR_FAILURE. You can retrieve the reason for the failure by calling PR_GetError.
